I've made it a habit now though where after I finish, before I pack the camera into the camera bag I revert my ISO back to 100, shutter speed to 1/60th and aperture to f/8. Gives me a decent starting point from which I can make adjustments when I take the camera back out of the bag.

As for the photos:

Number 2 and 4 seem the best however you still need to work on the composition.

In the shot with the UNO cards, the remote control at the bottom is distracting.

In the 4th picture, you should decide to keep that light on the right in the view or out, not halfway.
